Application filed October 12, 1914. Serial No. 866,312.

To all whom t may concern:

Be it known vthat I, HOWARD S. KIMMEL, a citizen of the United States, residing at Tiltin, in the county of Seneca and State of Ohio, have invented certain new and useful Improvements in Fluid-Pressure Cou-` pler-IIeads; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same, ref erence being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in automatic couplers for fluid pressure train pipes, the object in view being to produce 'a' simple and efcient device of this nature so arranged that, when two coupler heads come together, means is actuated for holding the gaskets of the two couplers together to make a tigh; joint and so arranged that the ycouplers will readily disconnect when two cars equipped with the apparatus are uncoupled.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a top plan view of two coupler heads connected together, and Fig. 2 is a central longitudinal sectional view through the same.

Reference now being had to the details of Y the drawings by numeral, 1 designates a coupler head with an air passage leading therethrough and to which a flexible hose 2 is adaptedto be connected in the usual way. The end of said coupler is aring and has a recess 3 formed about a nipple 4: formed therein and in which recess a gasket 5 is adapted to be seated, said nipple communicating with the passageway. The opposite inner face of the coupler is concaved as at 6 and is provided with a slot 7 Projecting laterally from the coupler head is a yoke 12 having apertured ends 10 for the reception of the screws 13 which pass through threaded apertures in the ribs 14 upon opposite sides of the coupler head. A brace, designated by numeral 15, is fastened at one end to the shank portion of the coupler head and its other end to said yoke and serves as a means for reinforcing the latter. Pivotally mounted upon said pin is a clamp 17 which is of the shape shown in the sectional view of the drawings, and a spring, designated by numeral 18, is fastened at its ends to said yoke and also bears against the clamp at one side of its pivotal center, the purpose of said spring being to normally hold the clamp in the position shown in the central longitudinal sectional view of the drawings. The arm of the clamp which is engaged by the spring is adapted to contact with a crosspiece 9 intermediate the slots to limit the throw of the clamp in one direction. l/Vhen the cla-mp is in its normal position, the inner edge of the end 19, which is slightly convexed, is flush with the inner concaved wall of the coupler, while the other end is positioned in the path of the `projecting portion 21 of another coupler of similar construction when the two come together for connection. Said yprojection 21, it will be noted, has ya conveXed surface 22 vadapted to conform to the concaved surface at the inner portion of the chambered part of the head when the two couplers are connected together. rlhe outer vedge of the projection 21 is provided withv a shoulder 23 which is adapted to be engaged by the convexed portion 19 while the other end of the clamp,

against which the conveXed end 22 contacts, will cause the clamp to tilt upon its pivot. The conveXed end 19 comes against said shoulder and has a cam action, tending to force the coupler head laterally so that the two gaskets will come in contact with each other and the nipples in registration, thus forming a tight sealed joint. As the clamping member tilts upon its pivot, the spring bearing against the same is put under tension so that, when the car couplers upon two cars upon which the fluid pressure coupling heads are mounted are disconnected, the coupler heads will pull apart, said clamps being actuated by said spring and thrown to its normal position.

Upon reference to the drawings, it will be noted that the clamp is slightly eccentrically mounted and, when two couplers come together to be connected, the convexed portion 22 of the coupler head will come in contact with the conveXed portion 17 of the clamping member 17 and cause the same to tilt upon its pivot 11 and will turn the clamping member from the position shown in Fig. 2 to the position shown in Fig. 1 where the view is broken away, and the projection 19 of the clamp will be turned to Contact with the shoulders 23 to the coupler head. When the clamping member is thrown'to the po sition shown in Fig. 1 of the drawings, the spring engaging the same will be under tension and will tend to return the clamping member to its normal position, shown in Fig. 2 when uncoupled and in which latter position the spring is not under tension. When the couplers are lockedtogether, it Will be noted that the convexed edge bearing frictionally against the edge 17 will positively hold the part 19 in its engaging relationy as shown.

When the coupler heads are connected as shown the gasket about the nipple inthe diagonally disposed portion will be forced under pressure against'the face of a gasket upon the other coupler head, thus forming a hermetically sealed joint.

When the cars equipped with our couplers are disconnected and a slight pull is given -to one ofthe coupler heads, the clamp member will turn upon its pivot and allow the coupler heads to be readily disconnected.

What I claim to be new is: j

l. A coupling device for fluid pressure pipes comprising coupler heads, each of which has a flaring end'which is recessed, the wall of the flaring portion being provided with a slot, said coupler having a convexed portion and shoulder upon one side thereof, a yoke xed to each head and a pin carried by the yoke, a clamping member pivotally mounted upon said pin and movable in said slot and having a projecting portion extending into the recess of the head, a lug, a spring engaging the clamping member,

the projecting portion of the clamp being in the path of and adapted to be struck by the convexed edge of a coupler head as two similar coupler heads come` together, vand said lug being adapted to engage a shoulder upon A the coupler head.

2. A coupling device for fluid pressure pipes comprising coupler heads, each of which has a Haring end which is recessed, the wall of the flaring portion being provided with a slot, said coupler having a convexed portion and a shoulder upon one side thereof, a yoke fixed to each head and a pin carried by the yoke, a clamping member having a cani edge and pivotally mount-l ed upon said pin and movable in said. slot and having a projecting portion extending into the `recess of the head, said clamping A.
